Description

Technical Field

[0001] The utility model relates to the field of stainless steel bars, in particular to a surface polishing machine for stainless steel bars. Background Art

[0002] Stainless steel bars are made from stainless steel ingots through hot rolling or forging. To meet market demands, some stainless steel bars are bent after production. However, during the processing of bent stainless steel bars, defects such as burrs and scale may occur on their surfaces. These defects not only affect the appearance but also may affect the performance and service life of the material. In the existing technology, it is relatively easy to polish the outer surface of bent stainless steel bars, but the polishing effect at the bent parts inside the bent stainless steel bars is not good, resulting in an incomplete polished surface. Consequently, the bent stainless steel bars still have defects such as burrs and scale. For this reason, a surface polishing machine for stainless steel bars is proposed. Summary of the Utility Model

[0003] The utility model aims to provide a technical solution to overcome the above deficiencies.

[0004] A surface polishing machine for stainless steel bars includes a support table. On one side of the top of the support table, a connecting frame is vertically arranged, and at the top of the connecting frame, a material grinding and placement table is horizontally arranged. The bottom end inside the material grinding and placement table is recessed downward. Horizontally arranged at the top end inside the material grinding and placement table is a transmission shaft, and the transmission shaft rotates at the top of the material grinding and placement table. The transmission shaft is sleeved with a roller, and the transmission shaft and the roller move in the same direction. The roller is horizontally located at the top end inside the material grinding and placement table. The roller is provided with a number of nuts, and the number of nuts are all horizontally arranged on the outer side surface of the roller, and the number of nuts and the roller move in the same direction. Thus, when the transmission shaft drives the roller to rotate, it simultaneously drives the number of nuts to rotate at the top end inside the material grinding and placement table, and any one of a grinding piece, an oilstone strip, a wool wheel, and sandpaper can be threadedly connected and installed on the number of nuts. Therefore, when the bent stainless steel bar is transported into the material grinding and placement table, the grinding tools connected to the number of nuts on the surface of the roller polish the bent surface inside the stainless steel bar.

[0005] Preferably, on the other side of the surface of the support table, a motor is arranged, and the motor is located on the side of the connecting frame. The motor is drivingly connected to the transmission shaft, and the motor drives the transmission shaft to rotate at the top end inside the material grinding and placement table.

[0006] Preferably, the motor is provided with a first driving wheel, and the first driving wheel is vertically located at the side of the exterior of the motor, and the motor is drivingly connected to the first driving wheel. The first driving wheel is drivingly connected to the transmission shaft, and when the motor drives the first driving wheel to rotate, the first driving wheel drives the transmission shaft to rotate.

[0007] Preferably, a second driving wheel is provided between the first driving wheel and the transmission shaft, and the second driving wheel is vertically located at the side of the transmission shaft. The second driving wheel is drivingly connected to the first driving wheel, and a belt is drivingly connected between the second driving wheel and the first driving wheel.

[0008] Preferably, a protective cover is provided between the connecting frame and the motor, and the protective cover is obliquely located at the sides of the connecting frame and the motor. One side of the protective cover covers the side of the first driving wheel, and the other side of the protective cover covers the side of the second driving wheel.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the transmission shaft drives the roller to rotate, it simultaneously drives a plurality of nuts to rotate at the top end inside the material grinding and placing table, and any one of a grinding disc, an oilstone strip, a wool wheel, and sandpaper can be threadedly connected and installed on each of the plurality of nuts. Thus, when the bent stainless steel bar is conveyed into the interior of the material grinding and placing table, the bent surface inside the stainless steel bar is in mutual contact with the roller. At this time, the transmission shaft drives the roller to rotate, and the grinding tools connected to the plurality of nuts on the surface of the roller polish the bent surface inside the stainless steel bar, thereby solving the technical problems of poor grinding effect and uneven grinding surface of the bent surface inside the stainless steel bar in the prior art.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1-4 , in the embodiment of the present invention, a surface polishing machine for stainless steel bars includes a support table 1. On one side of the top of the support table 1, a connecting frame 2 is vertically arranged, and a material grinding placement table 3 is horizontally arranged at the top of the connecting frame 2. And the bottom end inside the material grinding placement table 3 is recessed downward. Horizontally arranged at the top end inside the material grinding placement table 3 is a transmission shaft 4, and the transmission shaft 4 rotates on the top of the material grinding placement table 3. The transmission shaft 4 is sleeved with a roller 5, and the transmission shaft 4 and the roller 5 are in the same movement direction. And the roller 5 is horizontally located at the top end inside the material grinding placement table 3. A number of nuts 6 are arranged on the roller 5, and a number of nuts 6 are all horizontally arranged on the outer side surface of the roller 5, and a number of nuts 6 and the roller 5 are in the same movement direction. Thus, when the transmission shaft 4 drives the roller 5 to rotate, a number of nuts 6 are simultaneously driven to rotate at the top end inside the material grinding placement table 3, and a number of nuts 6 can be threadedly connected with grinding sheets, oilstone bars, wool wheels, sandpapers, etc. Therefore, when the bent stainless steel bar is transmitted into the material grinding placement table 3, the bent surface inside the stainless steel bar is in mutual contact with the roller 5. At this time, the transmission shaft 4 drives the roller 5 to rotate, and the grinding tools connected by a number of nuts 6 on the surface of the roller 5 polish the bent surface inside the stainless steel bar, thereby solving the technical problems of poor grinding effect and uneven grinding surface of the bent surface inside the stainless steel bar in the prior art.

[0019] On the other side of the surface of the support table 1, there is a motor 7, and the motor 7 is located on the side of the connecting frame 2. The motor 7 is drivingly connected to the transmission shaft 4, and the motor 7 drives the transmission shaft 4 to rotate at the top inside the material grinding and placing table 3, so as to drive the roller 5 and several nuts 6 on the roller 5 to rotate.

[0020] The motor 7 is provided with a first transmission wheel 9, and the first transmission wheel 9 is vertically located on the side surface outside the motor 7, and the motor 7 is drivingly connected to the first transmission wheel 9. The first transmission wheel 9 is transmission-connected to the transmission shaft 4, and when the motor 7 drives the first transmission wheel 9 to rotate, the first transmission wheel 9 drives the transmission shaft 4 to rotate.

[0021] A second transmission wheel 10 is arranged between the first transmission wheel 9 and the transmission shaft 4, and the second transmission wheel 10 is vertically located on the side surface of the transmission shaft 4. The second transmission wheel 10 is transmission-connected to the first transmission wheel 9, and a belt (not shown in the figure) is transmission-connected between the second transmission wheel 10 and the first transmission wheel 9. Thus, when the motor 7 drives the first transmission wheel 9 to rotate, it drives the second transmission wheel 10 to rotate and drives the transmission shaft 4 to rotate.

[0022] A protective cover 8 is arranged between the connecting frame 2 and the motor 7, and the protective cover 8 is obliquely located on the side surfaces of the connecting frame 2 and the motor 7. One side surface of one end of the protective cover 8 covers the side surface of the first transmission wheel 9, and one side surface of the other end of the protective cover 8 covers the side surface of the second transmission wheel 10. Thus, when the first transmission wheel 9 and the second transmission wheel 10 rotate, the protective cover 8 can isolate dust, preventing dust from adsorbing on the first transmission wheel 9 and the second transmission wheel 10 and affecting the rotation speeds of the first transmission wheel 9 and the second transmission wheel 10.
